A molecule is targeted to a leukemia cell by first contacting the cell with a retinoid in an amount effective to increase the expression of a marker in the cell, and the contacting the cell with an agent that specifically binds the marker. For directing a molecule to an acute promyelocytic leukemia cell, the cell is contacted with all-trans retinoic acid to induce or increase expression of CD52 on the cell. The cell is then contacted with a molecule, such as an anti-CD52 antibody, that specifically binds the CD52 expressed on the cell.
